Comparing PERC and TOPCon Solar Products: A Cost-Benefit Analysis

Hello Solar enthusiasts! Welcome to the space catering to all information and updates from the world of solar. Recent trends indicate that prices for Tunnel Oxide Passivated Contact (TOPCon) solar panels are seeing a steady decline. In simple words, TOPCon solar panels are a new breed of solar panels that promise better efficiency levels. In this post, let’s explore how this will affect the sales of solar panels that are based on Passivated Emitter and Rear Cell (PERC) cells.

Here‘s a scoop about price trends: there was a significant readjustment for modules that operated with an efficiency level exceeding 22%. The intriguing part? These modules are now primarily outfitted with n-type/TOPCon cells and double-glass. They are harmonizing their prices with those of mainstream modules. Now, you might know the naysayers always draw examples from modules using Interdigitated Back-Contact (IBC) or Heterojunction (HJT) technology. However, these are outliers and we won’t be considering them in this discussion.

Here’s something more fascinating: the production volume for n-type cells and modules seems to be skyrocketing in China. However, the new customs scenario in the USA may already be influencing trends. So, there’s a big question mark on the impact that it might have on the European market.

Let me share some insider info. Even though there are larger stocks of modules produced before or in 2023, they aren’t selling well due to their lower performance. Building owners are usually more inclined towards high-performance solar panels for their homes and latest technology, which creates a hurdle for older inventory to sell

A consequence of high inventories and other global market factors is that it puts additional pressure on solar panel prices. Old modules, originally produced and procured at much higher prices, thus need to continually readjust their market value.

Every country has its own challenges and strategies. For instance, Africa and Southeast Asia might soon become oversupplied with modules. The prevalent U.S. regulations restrict the Chinese solar companies from entering their market. A new approach catching momentum involves extending credit lines, often without demanding any security, and promising free delivery, rather than lowering module prices. However, it’s doubtful if this approach would be sustainable long term.

Converting these technical trends into simple strategy, I would say if you have surplus older modules at your disposal, consider installing them in large open-space or rooftop solar array for home. This way, you maintain better statics at a slightly increased material and assembly cost, balanced by the easy handling process.

Advantages are sprinkled everywhere, if observed keenly. These modules are already in stock and are thus guaranteed to be available. This means no issues with delivery and no setbacks in the construction timeline. If you’re lucky, you might even find a few idle inverters and cable reels, and there you have it, the components for your photovoltaic (solar) system – nearing completion!

Always remember, once your system is up, connected, and running, it hardly matters whether the modules used are from the latest generation or not, as the resulting assets can be sold regardless.

Drawing a closing line to this deep dive into the dynamic world of solar business and trends, it’s evident that the solar industry continues to evolve and adapt. However, one thing remains constant – the growing need for renewable energy and the integral role of solar within it. Returning next time with more industry insights, until then, shine bright!
